FEED-WATER PURIFIQER.

SPECIFICATION forming part of Letters Patent No. 377,390, dated February 7. 1888.

Application filed August 16, 1887. Serial No. 247,116. (No model.)

and useful Improvements in Feed-\Vater Puritiers, of which the following is a specification,

reference being had therein to the accompanying drawings.

This invention relates to apparatus for filtering and purifying water for fcedinglsteamboilers and for other purposes; and it mainly consists in the construction ofautoiuatic sprayvalves that,with reversing the current through the filter, will distribute the water uniformly, all as will be hereinafter more fully described and specifically claimed.

In the accompanying drawings, Figure 1 represents asectio-ial elevation of the entire apparatus; Figs. 2 and 3, a vertical section through center and a sectional plan of an air: siphon for admixing air with the water; Figs. rand 5, avertical cross-section and a sectional plan on lines: a: in Fig. 4. of the automatic spray-valve, and Fig. 6 is a modified construe tion of the spray-valve.

Corresponding letters in the several figures of the drawings designate like parts.

A denotes the tank, being preferably cylin-' drical, and that, as shown, may be open on top.

13 is the steam-pump, of any usual construction, with suction-pipe O and discharge-pipe 1). This pipeD communicates with a sprinklcr or rose-head, id, located in the top portion of tank A. A T-valve, F, is interposed in pipe 1), connecting abranch pipe, G, that pro vidcs communication with a chamber, H, whence a series of pipes, Lcurved on top, lead vertically down toward the bottom of the tank. From the bottom of chamber H also'leads vertically down a pipe, J, provided with three (more or less) star-couplings, K K K, with radialpipesLefdownwardly-inor-easinglength and dewnwardly-eurved ends. To the lower end of pipe J is coupled a strainer, M, having coupled again in its upper portion a horizontal pipe,'l i, having T-valvc 0, with vertical branch pi pc I and stop'valvc (g, and connect iug with the siphon it, that again has connected pipe 8, leading into the bottom of reservoir '1. Pipe-D, intermediate of valve F and sprinkler-head E, is provided with astop-valve, U. A'n J-verfl'ow-pipe, v\V, as well as pipe I leadsinto the sewer or other waste-water chain nel.

Each pipe I and L has coupled to its end an automatic spray'valve, Y, each consis'. -ng of a conical shell, 0, the plated of which has a cylindrical screw-nozzle, e, for connecting a pipe, I or L, and around this screw-nozzle e the plate (I is perforated with holes f. An annular valve, g, is fitted over the nozzle 0, to be guided thereon, and its conical rim is ground into the projecting rim of conical casing c. \Vater being forced through nozzle into casing a, While passing through perforations f, will raise valvey, squirting out a thin circular spraybetwcen the upper edge of easing c and the rim of valve g, thereby distributing the writeovera-largcsurt'acc and agitating the filter-bed, loosening all impurities and carrying them to the top of the tank.

The siphon It consists of a casing, h and Z, connected by ribs j. Into one side of easing h is screwed the end ofa pipe, N, and into the bottom end of easing i is coupled the pipe S. A nozzle, k, having a contracted lower end, is screwed into the bottom of casing 71, to form a continuation thereof, discharging into pipe S, and to form an annular air-channel, Z, around such nozzle k, that will communicate with the water-jet issuing from the mouth of such nozzle K. A tube, m, having a funnel -shaped head, a, and a contracted lower end, is pro jected through the top of easing it into nozzle lc, alsofor admitting air to intermingle with the jet of water forced thrmigh such nozzle K. The atmospheric air thus intermingled with the water and forced down in the bottom of the reservoir 1 will thereby provide a con tinuous supply of oxygen that will destroy all germs contained in the water, and will thereby preserve the water in a fresh and healthful state suitable for drinking.

The tank A being filled with gravel and sand, the operation of the apparatus is as follows, to wit: The valves l1 and 0 being closed and the valves U and Q being opened, the water lifted by the pump IE will be distributed by sprinkliugdrcad E over the surface of such gravel and sand, will. filter through the same, and will then pass oil" through strainer M,-pipe N, siphon It, and pipe S into reservoir 1, leaving behind all impuritiesand being refreshed by-the admixture of atmospheric air.

For washing out and removing the impurities collecting in the gravel and sand of tank A, which becomes necessary to be donefrom time to time, the valves V, O, andQ are closed and the valve F is opened, when the water forced by pump B will pass through pipe G into'box H, and thence through branch pipes I and L, squirting out from the automatic spray-valves Y,to be distributed through the gravel and sand, rising upward therein, and escaping through! overflow-pipe Vi into the sewer, and carrying with it-all the impurities collected in the gravel and sand. After thus being washed out the valve F is closed and the valves Vand O are opened, for the first water filtered through the gravel and sand again to pass ofi through pipe P into the sewer, and to carry off such impurities collected in the bottom of tank A during the time the current was reversed until the water filtered shows to be clear, when valve 0 is closed and valve Q is opened again for the filtered water to discharge into reservoir T. After each washing out the valves y will close again upon their seats in casing o by their own gravity, thus excluding sand or gravel from passing into and interfering with the operation of the automatic sprayvalves Y.

sidewise or downward, in which case a sprlng or other well-known mechanicaldevices may be applied for opening or closing the valves,- as shown iniFig. '6.

anywhere between the pump B and the filtering:tank for the purpose of destroying the germs and animal life therein before filtering the water. v i

What I claim is-- 1. In an apparatus for the purpose described, the spraying-valves Y, each consisting oi a conical shell, 0, a pipe'ooupling neck, e, perforated plate 01, fixed in the conical shell, and

shell, as set forth.

2. In an apparatus for the purpose described, the automatic spray-valves Y, each consisting of a conical shell, 0, with screw-neck e, and valve 9, guided on neck e, all substantiallyas set forth.
